What are Capacity Unit-Hours?

Data Refinery Flow, Profiling and Sampling jobs are charged for the number of whole or partial hours they run multiplied by the number of Capacity Units required per hour for each capacity type. At the moment, IBM supports only one capacity type in Watson Knowledge Catalog, which requires six Capacity Units per hour. A minimum charge of 0.96 Capacity Unit-Hours will apply for each job execution. A set number of free Capacity Unit-Hours are included in each plan for the month. For the Professional plan, charges will apply once the plan limit is reached for that month. For the Lite plan, once the plan limit for that month is reached, a data-flow or profiling job cannot be run until the next month or until the plan is upgraded to the Professional plan. Examples: 1) A Data Refinery Flow job runs for 30 minutes 0.5 hours x 6 Capacity Units Required Per Hour x USD 0.50 per Capacity Unit-Hour = USD 1.50 2) A Profiling job runs for nine minutes (profiling jobs can be automatically or manually triggered) The minimum charge applies in this scenario: 0.16 hours x 6 Capacity Units Required Per Hour x USD 0.50 per Capacity Unit-Hour = USD 0.48 3) A Data Refinery Flow job runs for 12 hours 12 hours x 6 Capacity Units Required Per Hour x USD 0.50 per Capacity Unit-Hour = USD 36.00
